准备工作
所用到的技术
- 腾讯地图微信小程序SDK
- 高德地图WebServiceAPI服务
- APP获取是否授权插件
- uview框架（不是必须）
接下来带大家去申请
腾讯地图微信小程序SDK
微信小程序JavaScript SDK
点击下载 JavaScriptSDK v1.2
然后去申请腾讯地图的 key
先创建应用 > 在添加key
在应用列表中就能看到我们申请的 key 了
高德地图WebServiceAPI服务
高德地图开放平台
高德地图这里只需要去申请一个 WebServiceAPI 服务的key
申请流程和腾讯地图一样
先创建应用 > 在添加key
APP获取是否授权插件
在 dcloud 插件市场添加 插件链接
直接使用 HBuilderX 导入到项目
选择自己的项目即可
uview框架
uview 框架这里就不写操作步骤了
大家根据步骤安装就行了
代码实现

注意（必看）
APP：如果你的APP时在开发阶段需要打开 定位功能
在项目的 manifest.json 中的 APP模块配置
